Specification of Letters Patent. Patented Feb.V 14,1922.

Application filed April 16, 1918. Serial No.- 228,898.

To all whom t .may concern:

Be it known that I, ALoID-n BRETAGNE, a citizen of France, and residentof Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and use` ful Improvements in Radiators, of whichthe following is a specification.

My invention is an improvement in radiators, of the type used inconnection with internal combustion engines for motor vehicles, and theinvention has for its object to provide a radiator formed from sectionsindependent of each other, and connected with common collectors ormanifolds and so arranged that any section may be cut out from thecirculation and removed without adecting the efficiency of the remainingsections.

Figure l is a sectional view of a motor vehicle hood showing theradiator in elevation and the collectors in section,

Figure 2 is a front View of a section detached, f

Figure 3 is an enlarged sectional detail showing the construction of thesections, and

Figure fi is a perspective view of a portion of one of the radiatingfins.

The present embodiment of the invention is shown in connection with thehood 1 of a motor Vehicle, the radiator sections which in the presentinstance are three in number being arranged within the casing andsupported in any suitable or desired manner.

Each of the sections comprises a pair of headers 2 spaced apart fromeach other, and. connected by a series of water pipes 3 which extendfrom one header to the other, and communicate with the headers at theirends. These pipes are arranged in spaced parallel relation, and theradiating ins 4 are arranged between the pipes, the said fins being asshown in Figure 4t channel shaped plates which are arranged insuperposed relation extending from the front to the rear of the section.A number of series of pipes is provided, each series being arranged in aplane extending from front to rear of the section, and the free edges ofeach series of plates 4 abut against the adjacent series of pipes. Eachheader has a connection 5 adapted for engagement with a pipe 6 whichleads to a common collector 7 and these collectors are connected withthe circulation system of the motor to receive the water therefrom anddeliver the water thereto. A valve 8 is arranged between each connectionand the adjacent pipe, and anyY of these valves may be closed whendesired. 'The sections "are clamped together by the clamps as shown inFigure l. Each of these clamps 9 embraces all of the sections of theradiator7 extending entirely around the sections and set screws 10 areprovided for holding the sections closely together. Should it benecessary for any reason, as for instance for repairing or cleaning, toremove a section, the valves 8 at the ends of the section are closed,the clamps are loosened, and the section is removed. The remainingsections may serve until a new section has been replaced or until theold section is repaired.

It will be v understood that as many sections may be used as may befound necessary or desirable, and the sections consist essen tially ofspaced headers connected by water pipes and having radiating fins inconnection with the pipes. The improved radiators may be easilytransported, since the sections may be separated, and the radiator maybe quickly set up when desired.

It will be noticed that the connection for the filling cap is with oneof the headers, preferably the header of the central section when an oddnumber of sections is used.

With reference to Figure 1 it will be observed that the branch pipes 6of the manifolds 7 are substantially less in diameter than the manifolds7 and may therefore be readily bent so that the manifolds may bepositioned for connection with the water circulating system of aninternal combustion engine. That is to say the manifolds 7 may beconnected with the upper and lower pipes or conduits kof an internalcombustion engine of any desired type. By reason of this construction itis not necessary to build the radiator for a particular type of engine.

1. A radiator comprising a plurality of vertically arrangedindependently removable sections having their upper and lower endsformed with headers, upper and lower manifolds having branch pipesdetachably connected to said upper and lower headers, a valve interposedin each branch pipe of the upper and lower manifolds whereby toindependently control the circulation of waterv through each section,and a plurality of spaced parallel transversel extending clampsembracing all the sections for deof spaced parallel transverselyextending clamps embracing all the sections for detaehably connectingthe same andhaving set screws engaging the side of one of the sections,said branoh pipes being substantially less in diameter than the diameterof said manifolds, whereby the branch pipes may be readily bent.
